Delivery fee = $7.50

Price per pizza = $14

Planned amount = $60

7.50 + 14p < 60

Subtract 7.50 from both sides

14p < 60 - 7.50

14p < 52.50

Divide both sides by 14

p < 52.50 / 14

p < 3.75

The one decreases, the other must increase to maintain the balance.

As the level of significance, α, decreases, the probability of making a Type II​ error, β​, increases. This is because Type I and Type II errors are inversely related. Type I error occurs when we reject a true null hypothesis, while Type II error occurs when we fail to reject a false null hypothesis.

If we decrease the level of significance, α, we are essentially making it more difficult to reject the null hypothesis. This means that we are less likely to make a Type I error, but more likely to make a Type II error.

In other words, as the level of significance, α, decreases, the probability of making a Type II​ error, β​, increases because the sum of α and β always equals 1. So if one decreases, the other must increase to maintain the balance.

Given the demand equation p+ 5x =40, where p represents the price in dollars and x the number of units, the elasticity of demand when the price p is equal to $5 is elastic.

Elasticity of demand is given as:

ED= dp / dx * x / p  where,dp / dx = 5 (-1 / 5) = -1x / p = 5 / (40 - 5) = 1 / 7

Therefore,ED = -1 * (7 / 1) = -7

The elasticity of demand is given as -7, which is elastic.

A small increase in price will result in a decrease in total revenue, and a small decrease in price will result in an increase in total revenue.

A unitary elastic demand would have resulted in an ED of -1, while an inelastic demand would have resulted in an ED of less than -1.

Therefore, demand is elastic when price is equal to $5.

The equation given in the question suggests that there is a direct relationship between price and quantity demanded, as an increase in price results in a decrease in quantity demanded.

When demand is elastic, consumers are highly responsive to price changes, and a small increase in price will result in a large decrease in quantity demanded.

MN = 52

since the 26 is right on a little line, tick mark or wtv, im no sure if MN= 78 or 52 but i'd just put 52. Sorry if im

wrongStep-by-step explanation:

Segment bisector is the line in half

The segment bisector of MN is JK and the measure of MN is 52.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

The only bisector of MN is JK and it is at the midpoint of the line segment MN so it will be a bisector.

Now,

Since JK is the bisector of MN

M(JK) = (JK)N

26 = (JK)N

So,

MN = 2(26) = 52

In the graph given, the line of reflection for the triangle XYZ and triangle X'Y'Z' is x=2.

Given, the coordinates of the triangle XYZ are:

X = (4,5)

Y = (6,3)

Z = (3,2)

and the coordinates of the triangle X'Y'Z' are:

X' = (0,5)

Y' = (-2,3)

Z' = (1,2)

for image of the triangle XYZ to get reflected and become X'Y'Z',

reflection of axis takes place.

But the images are not identical and symmetrical, so the reflection is not about y axis.

we check for x=2

hence reflection of axis when x=a is :

P(x,y) →x'(2a-x , y)

therefore use the above formula and check the coordinates of the reflected image.

X(4,5) → X'(2(2)-4 , 5)

x(4,5) → X'(0,5)

Y(6,3) → Y'(2(2)-6 , 3)

Y(6,3) → Y'(-2,3)

Z(3,2) → Z'(2(2)-3 , 2)

Z(3,2) → Z'(1,2)

hence x=2 is the reflection of triangle XYZ and X'Y'Z'.

Euler's method is a numerical method used to solve ordinary differential equations. It takes a small time step (h) and approximates the next value of the solution using the current value and the derivative at the current value. The formula for Euler's method is:

y[i+1] = y[i] + h * f(x[i], y[i]) where y[i] is the current value of the solution at x[i], f(x[i], y[i]) is the derivative of the solution at x[i] and y[i], and h is the step size. To compute the approximate y-values using Euler's method with a step size of 0.5, we can use the following table:

The joint moment-generating function of the number of registered cars and the number of cars that are not registered is \(e^{15(e^t + e^s - 2)).\)

The moment-generating function (MGF) of a random variable is the expected value of e^(tX), where X is the random variable and t is a parameter. The joint MGF of two random variables is the expected value of e^(tX + sY), where X and Y are the random variables and t and s are parameters.

In this case, we have two random variables: the number of registered cars (X) and the number of cars that are not registered (Y). X follows a Poisson distribution with parameter λ = 15, and the probability of being registered is p = 1/4. Y also follows a Poisson distribution with parameter λ = 15, but with the complementary probability of not being registered (1 - p = 3/4).

To find the joint MGF, we calculate the expected value of e^(tX + sY). Since X and Y are independent, we can express the joint MGF as the product of the MGFs of X and Y. The MGF of a Poisson distribution with parameter λ is e^(λ(e^t - 1)). Therefore, the joint MGF is e^(15(e^t - 1)) * e^(15(e^s - 1)).

Simplifying the expression, the joint MGF of the number of registered cars and the number of cars that are not registered is e^(15(e^t + e^s - 2)).

The solution of the given DE with the initial condition f(0) = 1 is:f(t) = u(t) + (cos t)/2 - (sin t)/2

The given DE is:

f(t) = 1 + t - s(t - u)f(u) du

To solve this DE using Laplace transform, we take the Laplace transform of both sides and use the property of linearity of the Laplace transform:

L{f(t)} = L{1} + L{t} - sL{t}L{f(t - u)}

Therefore,L{f(t)} = 1/s + 1/s² - s/s² L{f(t - u)}

The Laplace transform of the integral can be found using the shifting property of the Laplace transform:

L{f(t - u)} = e^{-st}L{f(t)}Applying this to the previous equation:

L{f(t)} = 1/s + 1/s² - s/s² \(e^{-st}\) L{f(t)}Rearranging the terms, L{f(t)} [s/s² +  \(e^{-st}\)] = 1/s + 1/s²

Dividing both sides by (s/s² +  \(e^{-st}\)),

L{f(t)} = [1/s + 1/s²] / [s/s² + \(e^{-st}\)]

Multiplying the numerator and denominator by s²:

L{f(t)} = [s + 1] / [s³ + s]

Now, we can use partial fraction decomposition to simplify the expression:

L{f(t)} = [s + 1] / [s(s² + 1)] = A/s + (Bs + C)/(s² + 1)

Multiplying both sides by the denominator of the right-hand side,

A(s² + 1) + (Bs + C)s = s + 1

Evaluating this equation at s = 0 gives A = 1.

Differentiating this equation with respect to s and evaluating at s = 0 gives B = 0. Evaluating this equation with s = i and s = -i gives C = 1/2i.

Therefore, L{f(t)} = 1/s + 1/2i [1/(s + i) - 1/(s - i)]

Taking the inverse Laplace transform of this,

L{f(t)} = u(t) + cos(t) / 2 u(t) - sin(t) / 2 u(t)Therefore, the solution of the given DE using Laplace transform is:f(t) = u(t) + (cos t)/2 - (sin t)/2

The initial condition for this DE is f(0) = 1.

Plugging this into the solution gives f(0) = 1 + (cos 0) / 2 - (sin 0) / 2 = 1 + 1/2 - 0 = 3/2

The general solution of the given system of differential equations is:

y = -37 × (1/2)x² + 5x + C, where C is the constant of integration.

The general solution of a system of derivative equations refers to a set of equations or formulas that represent all possible solutions of the given system. It includes an arbitrary constant or constants, which can take different values to yield different specific solutions.

The form of the general solution depends on the nature of the equations and the techniques used to solve them.

Here we have

dx/dt = 7x + y and dy/dt = -2x + 5y

To find the general solution of the given system of differential equations:

=> dx/dt = 7x + y  __ (1)

=> dy/dt = -2x + 5y  __(2)

Solve it using the method of simultaneous equations.

Solve Equation (1) for y:

y = dx/dt - 7x

Substitute the value of y in Equation (2):

dy/dt = -2x + 5(dx/dt - 7x)

Simplify the equation:

dy/dt = 5dx/dt - 2x - 35x

dy/dt = 5dx/dt - 37x

Rearrange the equation:

dy/dt - 5dx/dt = -37x

Multiply through by dt:

dy - 5dx = -37x dt

Integrate both sides of the equation:

∫(dy - 5dx) = ∫(-37x) dt

Integrate each term:

y - 5x = -37 * (1/2)x² + C

Simplify the equation:

y = -37 × (1/2)x² + 5x + C

Therefore,

The general solution of the given system of differential equations is:

y = -37 × (1/2)x² + 5x + C, where C is the constant of integration.
